Light-scattering element.

摘要

A light-scattering element comprising a liquid-crystalline material which is dispersed in a matrix of a transparent polymer material is manufactured by mixing at least one reactive liquid-crystalline material and at least one non-reactive liquid-crystalline material. The mixture is provided between two substrates 1 and 2 in the form of a thin layer 5, rubbed polymer layers 3 and 4 being present on the side of the substrates where the mixture is to be provided, as a result of which the molecules in the mixture are oriented. The reactive material is made to cure by means of actinic radiation thereby forming a polymer network in which the non-reactive material is present as a continuous phase. The difference between one of the refractive indices of the cured material and the corresponding refractive index of the non-reactive liquid-crystalline material is less than 0.10, as a result of which the light-scattering element forms a simple polarizer. <IMAGE>
